6( 5-8x) +12= -54I need help I didn't understand this problem it's really hard to solve it doesn't make sense to me please help?

Answers

Answer 1
Answer: 6( 5-8x) +12= -54 
30-48x+12=-54 this comes from distributing(multiplying) 6x5 and 6 times -8x
30+12-48x=-54 you have to add the coefficients 30+12
42-48x=-54  
-42        -42 
-----------------------
-48x=-96 divide by -48
x=2
Answer 2
Answer: You use the distributive property by distributing the 6 to 5 and -8x which gives you 30-48x+12=-54 then you subtract 30 and 12 from both sides to get -96 then divide by -48 to solve for x which gives you 2

Final answer:

The adjusted multiple coefficient of determination accounts for the number of independent variables in the model.

Explanation:

The adjusted multiple coefficient of determination, also known as the adjusted R-squared, is a statistical measure used in regression analysis to assess the goodness-of-fit of a regression model. It takes into account the number of independent variables in the model and adjusts the coefficient of determination (R-squared) to account for the degrees of freedom.

The adjusted R-squared provides a more accurate measure of the model's predictive power by penalizing the inclusion of unnecessary variables that do not contribute significantly to the model's explanatory power. It helps to prevent overfitting and provides a more reliable estimate of the model's performance.

W have been given that It takes 2 1/2 poster boards to display half of your project.

Here 2 1/2 poster boards = 2.5 poster board

Let you need poster boards would be x for your entire project

We can write this as a ratio as

2.5 poster board : 0.5 of project = x : 1 project

⇒ 2.5/0.5 = x/1

⇒ x = 25/5

⇒ x = 5

Therefore, you will need 5 poster boards for the entire project.
